Get to know SIM Only on Three:
What is a SIM Only deal?
A SIM Only contract is just that. No phone or tablet, just a SIM card with all the data, minutes and texts you need. Pick a Pay Monthly SIM or Pay As You Go SIM plan that suits you. We’ve got Pay Monthly phone contracts ranging from 1GB a month to Unlimited Data SIM cards. You get extra flexibility with Pay Monthly, because you can join us on a 1, 12 or 24-month plan. And if you choose Pay As You Go there’s no upfront cost.
Types of SIM Only deals
We offer 30-day, 12, and 24 month plans across 5G SIMs, Unlimited Data SIMs, and more, so you can choose a SIM Only plan that suits your lifestyle and budget.
How does SIM Only work on Three?
With a physical SIM, when it arrives, put it in your phone, and you’ll automatically get a text confirming that you’ve connected to Three. You’ll be ready to go in no time. The process for eSIM is even faster.
Switch to Three and keep your number
Moving your number across to Three is simple. You’ll need a PAC or STAC code from your current provider, and then it’s just a case of sending a text. Find out how to switch to Three.

And a huge range of data options, from 1GB to Unlimited data plans. And if you choose Pay As You Go there's no upfront cost. Simply send a text to switch to Three and keep your number.
